1'0 aZZ mi i/omit may concern: I

Be it known that 1, WILLIAM HART, a citizenof the United States, residing, at Kirksville, in {the county of Adair and State of .jects of the sameis to Missouri, have invented ,oertain new and useful Improvements in Graphephone Reproducers and I do declare thefollowing tobe a full, clear, and exact description of the invention, such as will enable-others skilled in the I art to WlQiQl1 'it appertains "to make and. use thesamei i This invention relates to reproduc'ers for graphophones, phonographs; V and other tell ing machinesg and one of the principal obromde' eans for pre venting the arring'orgoltingof the-stylus iii passing over the sound-grooves oi the record. Another object is to .proyide means -for.va-.

rying thevolume or givinggreater or less itInplitude to theproductiorgor reo'ordb, A I

These and other objects are attainedby means of the constrtiction illustrated in the plant by any suitable means,

accom anying drawmg; in whichkthefigure 1s a s1 e elevat on and partial SGGtlOHOf a reproduoer made in accordance withmyinvention.

. Referring to the drawingfor amore particular dBSCTlPtlOllOf my intention, the numeral 1 designates the horn-supporting elbow or intake of the reproducer, said elbow heing sup ported upon a 1 and the tube 2; esoilnd-box consists of ]vided with a springportion at 13, and a stylus 14 is securedto the outer end of said lever. Supported uponsaid lever is aweight 15, and supported upon the disk 4 is a weight 16. These weights may be secured in place as by pins orsmall screws (not shown) passin upward throu h the lever 11 and through t e disk 4 into t e weights. Projecting upwardly from the I asthe diaphra connected to t e stylus-lever any vibration ifoflthe stylus will be directly communicated v shiirttubularpi'ece 2 by means i of apin 3, formihgja i'vot between the elbow V weight lfi is an arm 17, and [secured to this arm atone end isxagspringw, the opposite end'of the s ring being connected to a pm 19, I

projecting ackfrom the elbow or intake 1. r 20 depends from the weight 16, and. a spring. 21 is secured to the depending arm' An arm at one end, and its opposite end is connected to a bar 22 .overhanging the Weight 15.

From the foregoing itwill be obvious that to the diaphragm and that the weights and .sprin s connectedto' the stylus-lever will have aten ency to give stability tothe stylusin its Y movement over the record and give increased amplitude to the reproduction. However,

should it be desired to produce a record withbe removed. In such condition the'finstrumerit may be used for teaching languagesor out'giving increased volume theweightfs may for the use of a type-writer and for other purposes not re V uiring a loud reproduction. .Various 0 anges in the form, proportion, and the minor details of construction may be resorted to without departing from the prin-. cipleor sacrificing any of the advantages of;

this invention. Having thus I claim as new, ters Patent, is-

. -1. In a reproducer oithe character de scribed, a diaphragm, a hub secured centrally thereto, a stylus-lever connected to said hub, a horn-intake, and a tube pivotally connected to said horn-intake, and disposed above'the upper end of said hub, substantially as de-' scribed.

2'. A reproducer for graphophones com,- prising a sound-box, a weight" thereon, a spring connected to said we ght and to the horn-intake, a weight supported upon the stylus-lever, and a sprin connected to said weight at oneend and aving its opposite is rigidly secured to a hub.

descr'ibed'my inventiom'w'hat and desire toseoure by Let-' endconnected to an arm dependin from the firstmentioned weight, substantia lyas described. p in testimony whereof I have hereunto set my hand in presence of twdsubsombmg witnesses.
